Tilt limiter for awnings

ABSTRACT

An arrangement of an adjustable tilt limiter with or without recoil lock within a mounting tube (2) for awnings, preferably for ones with tilt adjustment, has the tilt limiter mechanism (6) integrated within the mounting tube (2). A mounting cradle (4) is provided for supporting the tilt limiter which cradle is open on one side and is closed to the rear by a mounting plate (3). Bearing blocks act as pivot supports for an adjusting mechanism (6) for the tilt limiter (11). The mounting tube (2) has sections which join respective sides of the mounting cradle via short connection pieces (7) on the cradle which are telescopically connected to the respective mounting tube sections.

The invention relates to an arrangement of a preferably adjustable tiltlimiter with or without recoil lock in conjunction with a mounting tubefor awnings.

Such arrangements are known and are located around the mounting tube, onthe mounting tube or in front of the mounting tube, for example. On theone hand, reliable securing of a tilt limiter on the mounting tube isnot simple and this is mostly not very stable. On the other hand, anarrangement of the tilt limiter mechanism on the mounting tube orencircling it results in an unnecessarily large overall height andoverall depth around the latter which it is increasingly attempted toavoid. Furthermore, such arrangements, which often consist of a largenumber of parts, are also very complex and therefore expensive.

With respect to the state-of-the-art, an articulated awning with anadjusting shaft passing through the support tube is known from DE 28 34486 C 2, this possessing swivel bearings for the articulated armslocated on brackets, whereby the tilt angle of these arms can beadjusted by means of a worm fixed on the adjusting shaft and a wormwheel with internal thread acting in conjunction therewith via a thrustrod passing through the thread and an angle lever arrangement. Here,only the drive for tilt adjustment of the articulated arms is containedin the support tube.

Other arrangements of this type are known, for example, from DE-GM 80 05351, DE 32 06 963 C 2 and DE 34 47 792 A 1, as well as from DE 34 12 125C 1. Common to all these arrangements is that they possess a relativelylarge overall height and overall depth.

The task of the invention is thus to improve the stability of thearrangement of an adjustable tilt limiter in conjunction with a mountingtube, to reduce the overall height and overall depth, to considerablysimplify production and thus to make it considerably less expensive and,overall, to reduce the arrangement in all dimensions.

This is achieved by the invention owing to the fact that the tiltlimiter mechanism is integrated in the area of the mounting tube andthat the arrangement consists of a mounting cradle with bearing blockclosed to the rear by a mounting plate, whereby the bearing block actsas a pivoting support for an encapsulated adjusting mechanism for theactual tilt limiter, whereby the mounting tube adjoins both sides of themounting cradle and whereby the bearing block possesses axial bores forthe drive spindle of the adjusting mechanism of the tilt limiter.

It is particularly advantageous if the mounting tube adjoining bothsides of the mounting cradle is realized as a short connection piece ineach case which can be connected telescopically with the actual mountingtube.

It is of quite particular importance and above all economy if themounting cradle with mounting plate, bearing block, connection piecesfor the mounting tube and the holder consist of one piece.

Refer to the other claims for the details of further characteristics.

The invention will now be described in more detail on the basis of arealized example in conjunction with the enclosed figures.

The figures show the following:

FIG. 1 A schematic perspective view of a realized example of theinvention and

FIG. 2 A modified design form of the invention.

In FIG. 1, it is possible to see a tilt limiter arrangement 1 foradjustable awnings integrated in the area of the mounting tube. Thistilt limiter arrangement is located within the length of a mounting tube2 and consists of a mounting cradle 4, closed at its rear by a mountingplate 3 and at least partially open at the front and top, with bearingblocks carrying drive shafts 5 mechanism 6 of a tilt limiter 11, wherebythe adjusting mechanism is supported so that it has restrictedswivelling capacity and is preferably encapsulated. A connection piece 7adjoins this mounting cradle 4 on at least one side, but preferably onboth sides as shown, whereby these are connected telescopically withrespective sections of mounting tube 2.

It is possible either to insert the connection piece 7 in the mountingtube 2 as shown or to insert the mounting tube sections in theconnection pieces.

A holder 8 is provided on the rear of the mounting plate. Two bearingarms 9 for a tilting spindle 10, about which the adjustable tilt limiter11 can be swivelled, are located on the front of the mounting cradle 4.The tilt angle of this tilt limiter 11 can be adjusted by means of ascrew spindle 12. The tilt limiter is preferably also equipped with arecoil lock.

It is particularly advantageous if the mounting cradle 4 with bearingblocks 5, connection pieces 7, holder 8 and bearing arms 9 closed off bythe mounting plate 3 is made of one piece, e.g. cast.

On the other hand, it is also possible to use the design shown in FIG.2, where the tilt limiter arrangement consists of one piece with themounting tube 2 on at least one side, whereby the other side can thenpossess a connection piece.

If a tilt limiter arrangement with two, connection pieces 7 is used, themounting tube 2 is cut open as shown for the required location of thetilt limiter arrangement and the latter can then be fitted thereto. Thisarrangement has the additional advantage that individual remainingpieces of mounting tubes can still be used.

However, it must be noted that the mounting cradle may also be closedoff at the top by a semi-circular cover for example, which representsthe mating piece for the adjusting device 6. Furthermore, it ispossible, without deviating from the invention concept, to use aU-shaped mounting bracket instead of a mounting cradle 4 with mountingplate 3. The mounting tube sections or connection pieces 7 may alsopossess a square or round cross-section instead of a rectangularcross-section. Even a C-shaped mounting rail is covered by the inventionconcept.

It is therefore possible to see that the demands on which the inventionis based are fully satisfied.
